Fabulous little printer

Fabulous printer, saves me so much time no more sellotape sticking on labels, I highly recommend this fabulous printer , customer service is fabulous they answer all my questions I have straight away , so happy with my purchase I wish I had brought one years ago I wouldn’t be with out it now .Thank you Munbyn

Decent product and quick setup

This was pretty straight forward to setup. It all worked without much faff. Was expecting it to be more involved than it was and was expecting to waste a few labels on the process. But I got it to print what I needed quickly and didn't waste any labels.The print quality wasn't as great as I thought it might be, hence the 4 stars.

Easy and compact machine

I have never used a thermal printer before, and was pleasantly surprised how easy the set up is. Works out a lot cheaper than an inkjet printer if you are only printing labels or smaller items. It does only print in black but different coloured labels are available. The design space app is a nice bonus. I have not designed anything myself yet but it looks pretty straight forward and there are loads of ideas on there. It’s small and doesn’t take up too much room. I have just ordered a label roll stand to go with it. The only thing I didn’t like is that it doesn’t seem to go on stand by when not being used, like my inkjet printer does. So I have been turning it on and off when using it which is a bit of a pain if I am wanting to print from a different room

Easy to set up, great product- highly recommend

I’m actually very impressed with this lil printer - definitely get the sticker roll stand as it makes it work seamlessly- I had it printing with a design made on my phone using their app within, 5 mins of unpacking the box and setting up! So easy to set up.The brown stickers I brought aren’t real Kraft stickers but they still look convincing
